**NIP-05 (User-to-domain mapping)**
The Nostr protocol was born as a pure stream of signed events, with no hierarchies or authorities. Identity was the public key, period. Then came NIP-05: a bridge to DNS, to make handles readable and verifiable. It seemed like a harmless convenience. But that “verifiable” hid a mortgage: whoever owns the domain decides who is authentic. In a blink, the system leaned on a centralized infrastructure (registrars, DNS servers, certificate authorities). Clients began displaying the “@domain” username as a trust badge, pushing users to get their own domain or rely on third-party providers. The simplicity of the protocol cracked: now, to “be someone,” you must own a piece of the traditional web. It is no longer a pure marketplace of keys, but a hierarchy disguised as convenience. The alternative exists: use only the hex key, or local nicknames without external verification, and judge content by signature and context, not by domain. Another Nostr is possible if we stop delegating trust to DNS and return to bare cryptography.
